To find a No Caller ID number on an iPhone, there are two main effective methods:
- Use the *69 code to redial the last incoming call. Dial *69 in the Phone app keypad and press call. This can sometimes reveal the actual phone number of the last caller even if it was hidden. This works only for the most recent call and depends on your carrier and the caller’s settings.
- Download and install a caller ID app such as Truecaller or Hiya. These apps identify incoming calls by matching them against large databases, sometimes revealing the caller’s identity even if the number is hidden. However, these apps only work on calls received after the app is installed and require certain permissions.
Additional notes:
- The *69 method is free and quick but limited to the last call and carrier-dependent.
- Caller ID apps provide ongoing identification and spam blocking but require prior installation and data sharing.
- There is no built-in iPhone setting to reveal No Caller ID numbers for past calls.
- For callers hiding their number from others (showing No Caller ID), the iPhone setting "Show My Caller ID" can be enabled or checked.
These methods are the current practical ways to identify No Caller ID calls on iPhone.
